Fertilizing techniques for new vegetable fields

In recent years, due to industrial restructuring and urban expansion, and other reasons, some old vegetable fields were occupied, and some grain fields and wasteland were changed to vegetable fields. These new vegetable fields all have unfavorable factors such as shallow soil layer, poor permeability, poor cultivability, low soil organic matter content, low soil quality, lack of nutrients, and improper irrigation and drainage. Therefore, it is necessary to speed up fertilization to ensure soil nutrient balance and accelerate soil. Ripening, creating good soil conditions for the high yield of vegetables. The methods of fertility improvement are as follows: Deep ploughing and soil improvement: The grain quality of the grain field is generally poor. The tillage layer is only about 15 cm. It is changed to vegetable soil. Due to the increase in the number of planting ridges and the consumption of nutrients, the cultivating layer should be deepened gradually to improve its physical properties. Deep plowing time can be arranged in the summer and autumn when the vegetables are out of the garden, each deep-dip twice, so that the cultivation layer of 25-40 cm. Addition of organic fertilizer: To improve the soil structure, it is necessary to have substances that can stabilize the structure, such as modifiers, urban organic waste, and organic fertilizers. The application of organic fertilizer can not only supply the needs of vegetables for nitrogen, phosphorus and potassium, but also promote the formation of soil aggregate structure, improve the ability to retain water and fertilizer, and increase the buffer capacity of the soil. It is a material guarantee for fertilizing new vegetable fields. Should be given great attention.
Planting legume green manure: The legume green manure fixes the nitrogen in the atmosphere. After picking up the edible part of the legume, the returning of the crop straw, especially the peas, beans and other tender stems and leaves, can increase soil organic matter and nitrogen content. Rational rotation: Continuous cropping of vegetables can lead to soil acidification, salinization, and disease spread. In the grain reform area, special emphasis should be placed on rational rotation, making use of differences in the absorption of different types of vegetables, slowing down the excessive consumption of certain nutrients, and avoiding or alleviating the above-mentioned problems, so as to give full play to the potential of new vegetable fields. If some mustard, peas, etc. are arranged in the rotation, they can absorb phosphorus and potassium that cannot be used by ordinary vegetables, and 14%-34% of them are re-used in the soil in the available state to improve phosphorus and potassium for the next vegetable. Nutritional status. There are a variety of rotations, but one-quarter legumes should be arranged in the rotation. In addition, according to the specific conditions of each piece of land, it is necessary to take corresponding measures for the targeted treatment of “sickness”. For example, for the low-lying land that often encounters internal waterlogging, the problem of water must be solved; for acidic soil, calcareous fertilizer must be applied. The cultivation of new vegetable plots is a long-term task. It cannot be achieved in the short term. Various measures must be taken to ensure that the results are quite obvious. Localities can conduct fertilization according to local conditions.

In the era of relatively backward agricultural civilization, any spread of locusts, armyworms, borers and other pests will take big risk even low-yield crops, while the development of pesticides makes these pests under control, played an important role in the people's production and life and people health . The Birth of pesticide industry, greatly changed human history of completely dependent on the rice. Argo chemical  have widespread in Pesticides, as well as insecticides fungicides, acaricides, herbicides, plant growth regulating agents. The use of pesticides greatly increased agricultural production to ensure that the population growth has brought a lot of material needs, but also take the problem of residues of pesticides. We are committed to the development of efficient, low toxicity and residue pesticide products, the annual export volume exceeds hundreds of tons.
